Our fantastic civilization has fallen out of touch with many aspects of nature, and with none more completely than with night.

In memoriam Halton C. Arp (1927-2013).

Description:

Small, round spiral galaxy that is slightly elongated to the N-S. Its central region is moderately brighter than its disk. I estimate its dimensions to 1.5x2' with the center shining at about 13.5m and the surface at about 14m. I find the official 11m brightness catalogue data very misleading.
